  1. Infrared thermography in the diagnosis of Raynaud's phenomenon in vibration-induced white finger.

    Article - En anglais


    Frequent use of vibrating tools over several years may lead to a neurovascular disturbance of finger circulation with the development of typical Raynaud's phenomenon, attacks being triggered by vibration and/or cold exposure.

    The condition is recognized as an occupational disease and known as vibration-induced white finger (VWF).

    Aim of the present study was to evaluate the usefulness of infrared thermography (IRT) with a cold provocation test in the diagnosis of Raynaud's phenomenon in VWF.

    Patients and methods 

    24 patients with the diagnosis of VWF, previously, established by other methods, were compared with 12 matched control subjects.

    We carried out IRT-measurements simultaneously, on both hands before, directly, after and 5,10,15,20, and 30 minsfollowing a 3 min exposure ofboth hands to a waterbath of 12°C. The results of temperature measurements of allfingers were analyzed and the time to complete rewarming of all fingers was recorded.


    The basal thermograms did not differ between both groups, whereas the mean fill ger temperatures after cold exposure were significantly, lower in VWF-patients compared to controls, with a considerable individual overlap between both groups.

    Therefore, determination of absolute finger temperature reveals not to be a useful diagnostic tool in individual cases, but might be helpful for pharmacological studies (group-analysis). (...)
